I should mention that I 'm following the book Learn Ruby on Rails: Book Two by Daniel Kehoe, I use ZSH I'm working on OSX Captain.

I would greatly appreciate your help. I'm working on a new project on rails and am newbie in this environment

that in my Gemfile

end

回答1:

Change of config.action.mailer to config.action_mailer.

That's on the line that currently says: config.action.mailer.smtp_settings, Hence the error you are getting. config has a action_mailer method, but not action.
